The record

Purpose: Mobilizon is a platform for creating, sharing, and finding events and organizing communities.
Events: Users can create, modify, and delete events, save drafts before publication, share events by email or social media, and manage participation.
Groups: Groups can have public pages for activities and events, and can manage members and private content.
Discovery: Visitors can search for events, activities, and groups by keyword, place, or date.
Multiple identities: A single account can have multiple identities for different kinds of activities.
Federation: Mobilizon uses ActivityPub to share content between instances and interact with other Fediverse software.
Federation limit: Federation subscriptions are one-way, transmit only public content, and do not transmit events created before the subscription.
Integrations: Groups can provide RSS and ICS feeds, and the software supports event import and export in standard formats including ICS and RSS.
API: Each instance provides a GraphQL API for operations such as searching for and creating events; the API may differ between software versions.
Moderation: Instance administrators can moderate users, and unsolicited content can be reported and removed.
Privacy: The documentation says privacy settings and participant roles are supported, and event interaction is possible without registration.
Supported installation: Mobilizon can be installed from a precompiled release, Docker image, source, or a community-maintained NixOS module; documented release systems include Debian, Ubuntu, and Fedora versions listed in the install guide.
Hosting: The official site describes self-hosting as an option and directs visitors to Kaihuri for professional hosting services.
Support: Mobilizon documentation directs users to seek support on the forum or chat.
